Treyarch is committed to providing all gamers with the best online experience possible, and that means maintaining the games integrity. We have a zero tolerance policy against exploitation, and this is to protect the many gamers who go online to compete and have legitimate fun. Below is a brief outline of our security and enforcement policy which will remain posted and will get updated here.

The team at Treyarch has worked very hard to create a fun, competitive online environment, and we want to keep this environment clean so that the game can be played as it was intended. Users who abuse the game through modding, boosting, glitching or making offensive emblems degrade the online experience for others, and we will take action to prevent this from happening.

This was written by JD_2020 explaining how they are now banning members who have modded their stats:

Ensuring that Black Ops fans have the best possible online experience is of the utmost importance to Treyarch. In our continued effort to maintain the integrity and security of Call of Duty: Black Ops online, we are in the process of resetting stats and ranks on several Xbox 360 and PlayStation 3 players who have not earned them legitimately.

Boosting, glitching, and other forms of game exploitation hurt the overall experience for the majority of players that remain in good standing, and we want to reassure the community-at-large that we will remain vigilant in monitoring online gameplay per our posted Security & Enforcement Policy: (See above)

Weve recently been alerted to the fact that people are modifying their profile data to create fake gamertags with illegal characters and offensive words. If you do this, you will get permanently banned from playing Black Ops online and reported to Microsoft. Consider this fair warning.

Treyarch has a zero tolerance policy towards anyone detected as modifying their consoles or game data. Dont do it.

There was a small security breach on the Xbox 360 this week that allowed some players to artificially inflate their stats. In both instances, the team at Treyarch had hotfix patches for the security holes within hours. Our security team is reviewing all cases, enforcing bans and stats resets, and cleaning up the leaderboards. Players who were not active participants in these exploits but who were negatively affected by them will not get banned we have the ability to distinguish the modders/boosters from the innocent bystanders.

While the incident was isolated and fixed promptly, there are individuals who will re-post videos made during these brief windows in an effort to trick others into sending them money in exchange for rank boosting. These claims are false never send money or any other form of payment to anyone making such a claim. Not only is it a scam, but it is a violation of the console terms of service and the profiles will be banned from playing online.

Treyarch is committed to providing the best online experience possible for our fan base, and will continue to monitor and maintain the online integrity of Black Ops.

We are listening to you and weve been busy working on updates based on feedback from the community. We have already deployed a number of updates, and there will be many more to come. Stay tuned right here for all the latest info.
